Tutorials, Guides, Tips, and Tricks from Everyday Experiences

If you ever have the need to setup a program to run at a certain time, then the at is the command for you. Here’s the standard blurb from the man pages explaining what it is:

at and batch read commands from standard input or a specified file
which are to be executed at a later time, using /bin/sh.
at executes commands at a specified time.
atq lists the user's pending jobs, unless the user is the supe-
ruser; in that case, everybody's jobs are listed. The format
of the output lines (one for each job) is: Job number, date,
hour, queue, and username.
atrm deletes jobs, identified by their job number.

Now, I won’t reinvent the wheel on how to utilize the command. Instead, I’ll simply point you to this reference over at nixcraft (cyberciti.biz). Have fun!
